6 Claims. (Cl. 98108) This invention relates to an air register of the wall type ited State at O commonly designated as a baseboard register or difluser.

The main objects of this invention are:

First, to provide an air register in which the discharge of air may be effectively regulated to meet varying requirements as to volume without substantially varying the velocity of the air discharged.

Second, to provide an air register having a uniform velocity discharge with a control damper having adjustabie stop means for variably limiting the opening of the damper.

Third, to provide an air register with an adjustable bottom member or members which may be easily adjusted to facilitate installation and the connection of the register to a flue.

Fourth, to provide a wall register including a removable face member on which the damper and its associated parts are mounted facilitating the assembly of the parts and repairs and adjustments thereof as may be required.

Fifth, to provide a register having these advantages which is simple and economical in its parts and the assembly thereof and which may be readily installed and at the same time is attractive in appearance.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary front elevational view of a register embodying my invention, parts being broken away to show structural details.

Fig. 2 is an enlarged view in section on a line corresponding to line 2-2 of Fig. 1 with the damper in fully closed position.

Fig. 3 is a fragmentary view in section on line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary front elevational view showing certain details of the damper stop means.

Fig. 5 is an enlarged fragmentary view corresponding to that of Fig. 2 showing the damper in partially open position.

Fig. 6 is an enlarged fragmentary view on a line 6-6 of Fig. 1 illustrating the damper in closed position by full lines and in open position by dotted lines.

Fi 7 is a fragmentary view on line 7-7 of Fig. 2 showing details of the damper stop means.

The embodiment of my invention illustrated is designed as a wall register, that is. adapted to be installed against a wall which is conventionally indicated at 1 in Fig. 2. The floor is conventionally indicated at 2.

The housing of my improved register comprises a rear wall 3 having a forwardly projecting top flange 4 of substantial width and a forwardly projecting bottom flange 5. The end walls 6 are provided with inturned rear, top and front flanges 7, 8 and 9 respectively. The top and front edges of the end walls are contoured to the desired shape to support the front and'face member. The

ice

fit rear wall is secured to the rear flanges of the end walls as by means of the screws 10.

The front wall 11 is provided with an inwardly projecting bottom flange 12 and an inwardly projecting annular top flange 13, the arm of the top flange 13 projecting upwardly and inwardly. The flange 5 of the rear wall and the flange 12 of the front wall are disposed in a downwardly spaced relation relative to the lower ends of the end walls.

The face member 15 has a rearwardly projecting top portion 16 which is disposed between the top flange 4 of the rear wall and the top flanges 8 of the end walls. The top flange 4 of the rear wall is desirably folded inwardly upon itself to provide a smooth rounded front edge. The face member 15 is of general rearwardly stepped conformation, the front edges of the end walls being correspondingly stepped or conformed.

At its lower end the face member is provided with a forwardly olfset curved portion 17 terminating in an angled flange l8 seated upon the front wall. The lower end of the face member is secured to the face member by screws 19 engaging the arm 14 of the top flange 13 of the front wall. The front wall 11 is secured to the end walls by the fasteners, preferably screw fasteners, 20 while the face member is secured to the front flanges of the end walls by similar fasteners 20.

The face member 15 has an outwardly curved upwardly facing intermediate outlet portion 21 having a longitudinal series of vertically disposed rectangular discharge openings 22. The face member is provided with inwardly pro ecting brackets 23 and 24 on which the pivot arms 25 of the damper 26 are swingably mounted by means of the pivots 27. The bracket 23 is provided with a forwardly inclined and preferably curved stop member 28 eccentrically positioned relative to the pivots 27.

The damper is provided with an adjustable stop 29, desirably in the form of a screw which coacts with the stop 28 to limit the o ening movement of the dam er. The damper is curved to corres ond substantially to the curvature of the outlet ortion of the face member so that it c oses a ainst the inner s de of the outlet portion 21 of the re ister. as shown in Fig. 2.

The pivots 27 are desirably sli htly off center relative to the curvature of the out et portion of the face member so that clearance is provided when the damper swings from closed toward o en position and closes against the inner side of the outlet portion. However, the damper is suflicientlv close to the outlet openings in all its positions of adjustment so that the outlet area thereof is accurately controlled or a uniform volume control is pro ided without materially varying the velocity.

Otherwise stated the damper does not im ede the velocity flow of air through the register but does control the amount of air discharged. The clearance described is provided to insure free operation of the damper through its projecting handle 30 at the same time providing a tight closure when the damper is in fully closed position. The stroke of the damper may be easily and accurately controlled by adiusting the stop 29.

The flue 31 is desirably positioned centrally of the register housing but that is not always possible and also, flues are frequently of different dimensions. The flue is desirably provided with outturned flanges 32 which are disposed on the flange 5 of the rear wall and the flange 12 of the front wall. These flanges 5 and 12 also support the bottom members 33 which are slidable thereon below the bottom edges of the end walls, as is shown at the left hand of Fig. 1.

The rear wall is provided with a series of dimple like lugs 34 spaced to engage the upper sides of the bottom member where permitting their sliding adjustment.

In practice a single bottom sheet or bottom member is supplied with the register. This bottom member may be removed and cut to meet the particular flue'conditions and then the bottom member parts reinserted in proper relation to receive the flue between them. f

As stated, the structure illustrated is particularly designed as a wall register sometimes referred to as a diffuser, that is, air is diflused in a sheet like stream along and somewhat spaced outwardly from the wall.

The removable face member greatly facilitates the installation of the register and the damper being carried by the face member can be mounted therewith as a unit after the positioning of the register housing and the connection of the flue thereto. The completed structure is attractive in appearance.

I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate other embodiments or adaptations which I contemplate as it is believed this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
